The Streamlight ProTac 2L-X is a compact, portable flashlight that still provides a lot of output. Its powerful C4 LED has a maximum brightness of 500 lumens, and also features a low-power mode for longer-lasting illumination. Its strobe function allows you to signal to friends or disorient foes, and its TEN-TAP program switch selects between three programs to give you quicker access to the modes you need: high/strobe/low, low/high, and high only. Its dual fuel system allows it to run off the two included CR123A batteries or a Streamlight rechargeable 18650 lithium battery, and its Solid State power regulation ensures constant output as the batteries drain. The flashlight is made from rugged anodized aluminum for maximum impact resistance, and also boasts an IPX7 water resistance rating. It comes with a tough nylon holster for portability, and can also be carried on its removable pocket clip.
